ENDOGENIZING CONSUMPTION IN THE INPUT‐OUTPUT MODEL: THEORY AND APPLICATION

Since the basic model of input‐output analysis does not take into consideration the income effect on consumption expenditure, we constructed a model which endogenizes consumption and breaks down integrated production inducement into Leontief and Keynesian effects in a generalized context and in two solution approaches. Using short‐term marginal consumption propensities, we estimated that Keynesian effects make up about 14% of the integrated inducement effects for Japan. The public services sector, which is not influential in the basic model, becomes very influential in consideration of Keynesian effects. Manufacturing and service sector products are the main targets of the expanded consumption. The impact of a change in exogenous final demand can be easily simulated by applying the suggested apparent input coefficient matrix to the integrated inverse matrix.     

A note on interactions-driven business cycles

Within the standard Keynesian multiplier framework, extended by a micro-model of interactive formation of individual consumption propensities, we demonstrate that socioeconomic interactions can lead to cyclical fluctuations in aggregate economic activity. The underlying micro-model of direct interactions is a version of Alan Kirman’s generic opinion formation model, with an additional feedback effect from macroscopic variables on the transition probabilities. Our model engenders cyclical fluctuations of economic variables, despite the fact that neither the Keynesian multiplier model nor Kirman’s model does so on its own.

Some Early Multiplier Models of the Relationship between Income Distribution and Production Structure

Early efforts to endogenize consumption and hence to model the inter-relationships between production structures and income distribution via multiplier models are reviewed in this paper. It is suggested that, unlike the multipliers in Pyatt et al. (1973), the so-called Miyazawa multipliers cannot be sustained in the context of a model of the distribution of income among institutions (households, companies, etc) i.e. the institutional distribution of income. They can, however, be sustained within a model of the distribution of income among factors, i.e. the factorial distribution of income. Both distributions are modelled by Pyatt & Round (1979) which therefore provides a more general framework for analysing the relationship between the distribution of income and the structure of production.     

Demand,Structural Interdependence,and Economic Provisioning

Industrial and post‐industrial economies are characterized by a high degree of structural interdependence. Once an economy attains a level of economic development in which the technology enables a substantial portion of the population to enjoy a standard of living significantly above subsistence, “the material needs” of the system become difficult to define because they are interconnected with the relations of production in complex ways. In particular, demand comes to play a key role in the subsequent development of the system. This article presents an intersectoral model that integrates Keynesian and Kaleckian elements onto the classical surplus approach. The aim of the model is to provide a non‐neoclassical framework that can be used to analyze how demand, income distribution, and production are interconnected.     

THE ROLE OF SUPPLY CONSTRAINTS IN MULTIPLIER ANALYSIS

Multiplier analysis based upon the information contained in Leontief's inverse is undoubtedly part of the core of the input–output methodology and numerous applications and extensions have been developed that exploit its informational content, both at the national and regional levels. Nonetheless there are some implicit theoretical assumptions whose policy implications need to be assessed. This is the case for the ‘excess capacity’ assumption, which implies that resources are available as needed to adjust production to new equilibrium states. In an actual economy, however, new resources are often scarce and always costly. When supply constraints intervene, the assessment of the effects of government demand policies may be substantially different from that of the standard Leontief multiplier matrix. Using a closed general equilibrium model that incorporates supply constraints, we perform some simple numerical exercises and proceed to derive two ‘constrained’ multiplier matrices, based upon the implicit Jacobian matrix, that can be compared with the standard ‘unconstrained’ Leontief matrix.     

The Microfoundations of the Keynesian Multiplier Process

A theoretical foundation for the Keynesian multiplier process is derived from a simple model in which economic interactions are coordinated by a decentralized and self-organizing network of adaptive business enterprises. Deviation amplification arises from business failures that interrupt the flow of trading, and does not depend directly on lack of price-flexibility. Numerically the model produces almost the same hump-shaped impulse-response pattern as exhibited by GDP data in the United States.     

On the Mythology of the Keynesian Multiplier: Unmasking the Myth and the Inadequacies of Some Earlier Criticisms

Keynes’s multiplier story invites acceptance by building on the fact that people typically consume only a fraction of their income and that such purchases are incomes for sellers. By misrepresenting the classical definition of saving and the meaning of Say’s Law, Keynes laid the grounds for extolling the virtues of consumption spending as determining income and employment growth. But the mythology of the multiplier story becomes clear when we ask, “From where do people find the means to purchase consumption goods, other than production?” The inadequacies of several earlier criticisms stem from their failure to focus on this fundamental point.     

Property taxation and the demand for housing: An econometric analysis

There is disagreement among economists regarding the effect of a local increase in property taxation on the housing market. In defining the price of housing services studies of the demand for housing have treated the property tax exclusively as an excise tax on housing consumption. Two recent theoretical developments suggest this is a misrepresentation of the tax. One theory holds that the excise effects of property taxation may be shifted backward to the factors employed in the production of housing. The other theory concludes that the property tax is not an excise, but rather serves as an efficient price for local public services. To investigate these hypotheses, data from the Annual Housing Survey were employed to estimate a housing demand model which included the net effective property tax rate among the set of independent variables. In addition to revealing the property tax-housing demand relationship, the model provides more reliable estimates of income and price elasticities by eliminating specification errors found in previous studies. Results indicate that the property tax reduces the housing consumption of central city homeowners, but does not distort the suburban housing market.     

CRASS KEYNESIANISM

Keynesianism supports make-work schemes without regard for consumers' preferences. The impact of fiscal and monetary policy in corrupting the flow of inter-temporal production is entirely discounted. Where Keynes argued that long-term considerations should not obstruct the implementation of short-term palliatives for immediate problems, Keynesianism fosters belief in the judgement of the state across a wide range of expenditures. In effect, however, Keynesian concepts of aggregate demand and the income multiplier set no basis for sound economic policy.     

The Federal Housing Administration (FHA), tenure choice,and residential land use

This paper extends the standard, urban, residential land-use model to analyze the effects of Federal Housing Administration (FHA) mortgage insurance. On the demand side, households are differentiated by income and tenure; on the supply side, the cost of housing is related to the asset prices of land and structure and the cost of capital. Hypothesizing that capital cost is a function of household tenure and income, tenure is chosen to minimize this cost. The effect of FHA, then, is to expand the housing consumption of moderate-middle income households, by reducing their capital cost, while displacing those whose cost is not reduced.     

New Keynesian dynamics in a low interest rate environment

Recent research has found that the dynamic properties of the New Keynesian model are unorthodox when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity and the size of the government purchase output multiplier is very large. This paper provides evidence that these results are not empirically relevant. We show that a prototypical New Keynesian model fit to Japanese data exhibits orthodox dynamics during Japan's episode with zero interest rates. We then demonstrate that this specification is more consistent with outcomes in Japan than alternative specifications that have unorthodox properties.     

Interindustry Analysis with Social Accounting Methods

This paper evaluates the role of income-expenditure linkages in interindustry analysis. Using matrix decomposition methods and a social accounting matrix of the USA, it is shown that multiplier estimates which omit such linkages are not reliable measures of the effects of exogenous shocks upon industrial output and income. The paper further applies the decomposition method to study relative income determination between sectors, i.e. how the composition of national product changes in response to exogenous shocks.     

THE RELATIVE IMPORTANCE OF EXPORTS IN DETERMINING LEVELS OF REGIONAL OUTPUT AND INCOME: A Model and Empirical Evidence from Kenya

Exports have long been assumed by many to be the most important variable in driving regional growth, although factors such as government expenditure, investment demand, and remittances, among others, have also been recognized as significant. In addition, supply-side constraints to the promotion of regional growth and development have recently received increased attention in the literature. This paper evaluates the relative importance of exports, investment demand, and remittances, as well as supply-constrained agricultural production, in determining levels of regional output, value added, and household income in a single region in Kenya. The analysis is based on a mixed endogenous/ exogenous model derived from a social accounting matrix (SAM) which allows for incorporation of both demand and supply-side considerations. The paper finds that exports are, in fact, the most important factor in explaining regional output and wage income in the region studied, although not overwhelmingly so. In addition, the analysis demonstrates the importance of supply-constrained agricultural production as a determinant of income at the household level.     

EVALUATING SUPPLY-SIDE AND DEMAND-SIDE SHOCKS FOR FISHERIES: A COMPUTABLE GENERAL EQUILIBRIUM (CGE) MODEL FOR ALASKA

This study used computable general equilibrium (CGE) models to investigate the economic effects of three exogenous shocks to Alaska fisheries: (1) reduction in pollock allowable catch (TAC); (2) increase in fuel price; and (3) reduction in demand for seafood. Two different model versions, ‘Keynesian’ and ‘neoclassical’, were used to estimate impacts on endogenous output, employment, value added, and household income. By using a CGE model, this study overcomes the limitations of fixed-price models (such as input–output models) including (1) inability to calculate welfare effects due to fixed prices; and (2) difficulty of addressing supply-side shocks. There are currently few examples of CGE studies addressing fisheries issues appearing in the literature. Among those, this study is unique in that it uses a relatively disaggregated sector scheme and examines both supply-side and demand-side shocks.     

Project Appraisal for the Keynesian Investment Planner

This paper outlines a theory of project appraisal wherein the neoclassical premises of conventional cost-benefit analysis are replaced by their Keynesian counterparts. The paper shows how the social rate of return on public and private investment, the private and social discount rates, and other concepts used in cost-benefit analysis may be modified to take account of the income externalities generated by the multiplier, mark-up pricing, and the causal priority of investment over saving. This revised version was published online in July 2006 with corrections to the Cover Date.     

Quantitative easing and the loan to collateral value ratio

We study optimal monetary policy in a New Keynesian model at the zero bound interest rate where households use cash alongside house equity borrowing to conduct transactions. The amount of borrowing is limited by a collateral constraint. When either the loan to value ratio declines or house prices fall, we observe a decrease in the money multiplier. We argue that the central bank should respond to the fall in the money multiplier and therefore to the reduction in house prices or the loan to collateral value ratio. We also find that optimal monetary policy generates a large and persistent fall in the money multiplier in response to the drop in the loan to collateral value ratio.

苹果消费需求影响因素的实证分析

苹果是我国居民重要的生活消费品。本文在分析影响苹果消费需求因素的基础上,运用一元和多元线性回归模型对各主要影响因素的影响程度进行了实证分析。研究表明:苹果消费需求对人均可支配收入与城市化水平的反应较为敏感,且呈现正相关关系;但苹果消费需求对苹果平均价格弹性不足,呈现负相关关系。因此应该提高居民收入水平,稳步推进城市化建设,进一步拉动居民的苹果消费需求。     

DISTRIBUTIONAL INVARIANCE AND THE DESIGN OF SAMS

The decomposition of a matrix multiplier derived from a social accounting matrix (SAM) by Pyatt and Round [(1979). Accounting and Fixed Price Multipliers in a Social Accounting Matrix Framework. Economic Journal, 89, 850–873] has prompted a number of subsequent applications. In one of the earliest examples Stone [(1985). The Disaggregation of the Household Sector in the National Accounts, Chapter 8. In: G. Pyatt and J.I. Round (eds.) Social Accounting Matrices: A Basis for Planning. Washington, DC, The World Bank, 145–185] made the intriguing observation that the higher order (circular) effects of an exogenous change in final demand on the distribution of income and the structure of production were more or less independent of the sectoral composition of the initial injection. Our initial objective in this article is to explore this phenomenon of distributional invariance and to derive sufficient conditions for it. We then argue that these conditions have important implications for the design of SAMs, for the taxonomies they adopt and for levels of disaggregation, all of which strongly condition the quality of results that can be generated via subsequent modelling.
